What Is Atrial Fibrillation? Atrial fibrillation, often referred to as afib, is an irregular heartbeat, a rapid heartbeat, or a quivering of the upper chambers of the heart, called the atria. Atrial fibrillation is due to a malfunction in the heart's electrical system, and is the most common heart irregularity, or cardiac arrhythmia. For more detail about how the heart works and what happens to the heart when it is in atrial fibrillation, see About the Heart.

Overview Atrial fibrillation. Overview. Atrial fibrillation is an irregular and often rapid heart rate that can increase your risk of stroke, heart failure and other heart-related complications. During atrial fibrillation, the heart's two upper chambers (the atria) beat chaotically and irregularly — out of coordination with the two lower chambers (the ventricles) of the heart. Atrial fibrillation symptoms often include heart palpitations, shortness of breath and weakness.

How Atrial Fibrillation Progresses Longstanding persistent — continuous afib that lasts longer than one year. Permanent — continuous atrial fibrillation in which a decision has been made by the patient and the doctor not to try to restore normal sinus rhythm by any means, including catheter or surgical ablation.

A Look at Paroxysmal Atrial Fibrillation Causes of AFib. AFib is caused by damage to the heart from heart disease or high blood pressure. Medications and other factors can also lead to AFib. These factors include: binge drinking, or consuming 4 to 5 drinks within 2 hours. stimulant medications and drugs, such as methylphenidate, pseudoephedrine, or cocaine.

What Are the Treatments for AFib? Atrial fibrillation is a problem with your heart's electrical activity. You and your doctor have treatment options if your symptoms become too severe. With AFib, your heart quivers, beats too quickly, or skips beats.

- Atrial fibrillation (also called AFib or AF) is a quivering or irregular heartbeat (arrhythmia) that can lead to blood clots, stroke, heart failure and other heart-related complications. At least 2.7 million Americans are living with AFib. Here’s how patients have described their experience:

What are the Symptoms of Atrial Fibrillation (AFib or AF)? The most common symptom: a quivering or fluttering heartbeat Atrial fibrillation (AFib) is the most common type of irregular heartbeat. The abnormal firing of electrical impulses causes the atria (the top chambers in the heart) to quiver (or fibrillate).View an animation of atrial fibrillation. *Chest pain or pressure is a medical emergency. 2  You may be having a heart attack. 3  Call 9-1-1 immediately. 4  Paroxysmal fibrillation is when the heart returns to a normal rhythm on its own within 7 days of its start.

A Look at Paroxysmal Atrial Fibrillation If so, you may have atrial fibrillation. Atrial fibrillation occurs when the atria, or upper chambers of the heart, lose their normal rhythm and beat chaotically. It’s commonly known as AF or AFib. When it happens, blood doesn’t flow through the heart and body efficiently.

Amiodarone for Atrial Fibrillation Persistent or chronic atrial fibrillation is the type of atrial fibrillation that persists for more than 7 days once it comes on. In patients with persistent atrial fibrillation, the atrial fibrillation usually lasts until a normal heart rhythm is restored by treatment.

Atrial fibrillation or flutter Atrial fibrillation or flutter is a common type of abnormal heartbeat. The heart rhythm is fast and most often irregular. When working well, the 4 chambers of the heart contract (squeeze) in an organized way. Electrical signals direct your heart to pump the right amount of blood for your body's needs.

What Is Atrial Fibrillation? What Does Atrial Fibrillation Feel Like? Different patients have different symptoms. Some patients describe afib as feeling like skipped heartbeats, followed by a thud and a speeding up or racing of the heart. Others describe it as an erratic heartbeat, strong heart palpitations, or simply a rapid heart rate.

Atrial Fibrillation  (AF) Atrial fibrillation is an irregularity of the heart rhythm that increases the risk of stroke and death, particularly in the elderly. One way of treating it is to change this abnormal rhythm to a normal sinus rhythm using specific drugs or by delivering an electric shock to the heart.

Atrial fibrillation Atrial fibrillation (AF or A-fib) is an abnormal heart rhythm characterized by rapid and irregular beating.Often it starts as brief periods of abnormal beating which become longer and possibly constant over time. Most episodes have no symptoms.trial fibrillation is the most common serious abnormal heart rhythm. In Europe and North America, as of 2014, it affects about 2% to 3% of the population.

- What is Atrial Fibrillation? Atrial fibrillation is an abnormal heart rhythm that originates in the top chambers of the heart. With atrial fibrillation, the SA node does not direct the heart’s electrical rhythm. Instead, many different impulses rapidly fire at once, causing a very fast, chaotic rhythm in the atria.
